In order to be able to have an increased melt viscosity during the baking process, it is proposed that the thermo-hardenable, water-based hot-melt adhesive varnish layer also have a pre-cross-linking agent that bonds with the epoxy resin or with a mixture of epoxy resins, the pre-cross-linking agent being an organic amine with three amino groups, namely an organic triamine or a mixture of such organic amines.

Abstract: A method for producing thermomechanically produced hot strip products having improved mechanical properties is provided. A steel alloy is melted and adjusted so that a recrystallization during hot rolling at greater than 800° C. is suppressed. The melted steel alloy is cast into slab ingots and after being heated to a temperature above Ac3, the slab ingots are hot rolled until they reach a desired degree of deformation and strip thickness. The strip is then cooled to room temperature and is hardened by briefly reheating to a temperature above Ac3 and cooling again. The reheating takes place with a rapid temperature increase of more than 5 K/s and is maintained at the targeted temperature for a period of 0.5 to 60 seconds before cooling to yield the improved mechanical properties.

The housing body delimits an interior space which is open at one side by means of a housing opening. The frame part has a circumferential web surrounding the housing opening. Extending within the circumferential web is a central web of the frame part that divides the housing opening into at least two opening portions. A cover abutment surface is formed, against which the covers bear in their closed position. An encirclingly closed flameproof gap is formed between each cover and the cover abutment surface when the cover is situated in the closed position and is detachably fastened by means of one or more connecting units to the frame part.

Abstract: A protective housing in explosion-protection-type pressure-proof encapsulation. At least one device for reducing explosive pressure is associated with the housing. The housing includes a first housing part having a first sealing surface and a second housing part having a second sealing surface, wherein, when the housing is in the closed pressure-proof state, a resilient seal is held between the first sealing surface and the second sealing surface so as to be elastically deformed, and, as a result, closes the space between the first sealing surface and the second sealing surface in a flame-proof manner in the event of an explosion inside the housing. The flame-proof arrangement can replace a planar gap between, for example, a surface of a cover and a surface of a housing part, which gap requires conformity to relatively narrow manufacturing tolerances.

Abstract: A tap hole filling device for an electric arc furnace (1) includes a pivot arm (30) pivotable between a parking position and an operating position, a pivot arm actuator (40), an actuator link mechanism (50), and a refractory filling material dispenser (60) attached to an end portion (31) of the pivot arm to dispense refractory filling material (S) from a dispensing opening thereof while the pivot arm is in the operating position. The actuator link mechanism includes a connector (51) that is moveable between a connecting position, where the connector connects the pivot arm and the pivot arm actuator such that the pivot arm actuator (40) can pivot the pivot arm between the parking position and the operating position in an automatic operation mode, and a disconnected position, where the connector does not connect the pivot arm and the pivot arm actuator, to enable a manual operation mode.

Abstract: The invention relates to an explosion-proof arrangement (10) with an explosion-proof housing (11) which has a wall opening (23) in a housing wall (12). The wall thickness (d) of the housing wall (12) is so small that it is not possible to form a thread there in order to screw in a connecting body (15) for a line to pass through or for receiving an assembly so as to ensure protection against flame transmission. According to the invention, a connecting body (25), which has a flange (38) with a flange face (39), is inserted into the wall opening (23). The flange face (39) delimits a flameproof gap (58) by way of the housing wall (12). The dimensions of a gap or intermediate space between the connecting body (25) and a boundary face (24) of the housing wall (12), which boundary face delimits the wall opening (23), are not important. The protection against flame transmission can be provided solely by the flameproof gap (58) between the flange face (39) and the housing wall (12).
